Question

you have a graduated cylinder that you use to measure volume. the cylinder is marked in 1 ml increments. which measurement made using this cylinder contains the correct number of significant digits?
a. 75.333 ml
b. 35.5 ml
c. 21 ml
d. 320.01 ml

Explanation:

Step1: Understand significant digits in measurement

The graduated cylinder is marked in 1 ml increments. The measurement should be reported to one - decimal place as the uncertainty is in the tenths place for a 1 ml - increment device.

Step2: Analyze each option

• Option A: 75.333 ml has more precision than the instrument allows.
• Option B: 35.5 ml is reported to the correct precision (tenths place) for a 1 ml - increment graduated cylinder.
• Option C: 21 ml does not use the precision of the instrument.
• Option D: 320.01 ml has more precision than the instrument allows.

Answer:

B. 35.5 ml
